I have a bit of a bastard plumbing joint which resides directly under a main doorway in my house. I recently needed to cut into the flooring in order to make a repair.
I've dealt with trapdoors in my homes on and off forever but never something in such a high traffic area. This area is tiled with thin laminate style which I need to match on the top of the trapdoor.
What is the most appropriate method for keeping the seam sealed but still allowing access?
EDIT - per request here is an image. The access panel is about 12x18 and ends about in the middle of a door frame.
